Abstract (en)
[origin: EP0853252A2] Disclosed is a display device (Da) comprising an optical waveguide plate (12) for introducing light thereinto, and a driving section (16) provided opposingly to the back surface of the optical waveguide plate (12) and including a number of actuator elements (14) arranged corresponding to a large number of picture elements, for displaying, on the optical waveguide plate (12), a picture image corresponding to an image signal by controlling leakage light at a predetermined portion of the optical waveguide plate (12) by controlling displacement action of each of the actuator elements (14) in a direction to make contact or separation with respect to the optical waveguide plate (12) in accordance with an attribute of the image signal to be inputted; the display device (Da) further comprising a displacement-transmitting section (32) for transmitting the displacement action of the actuator element (14) to the optical waveguide plate (12), wherein a plate member (32a) of the displacement-transmitting section (32) is constructed by a white scattering element, and a color filter (40) is formed at a position corresponding to each of the actuator elements (14), on the back surface of the optical waveguide plate (12).
